It was created on June 6, 1984, as the first model of ant colony structure and the behavior certain members of the colony.  Dr. Tetrisov&amp;#039;s primary research interest was in designing a model worker ant behavior he had observed in his laboratory ant farms.  He had noted that as the ants gathered food and building materials, they appeared to be organizing the materials into specific patterns.  Worker ants would work in pairs, with one acting as the retriever of materials and the other acting as the organizer.  He further observed that the ants seemed to be quite competitive and that the most successful teams were awarded sweet juices from the queen as well as small pieces of straw.  The straw seemed to serve no purpose other than to be used by teams of worker ants to tally &amp;quot;points&amp;quot; they had amassed in their organizational competitions.  Dr. Tetrisov designed a simple computer program in which the user could mimic this observed behavior.  He named the program Tetris to signify that he was the primary programmer.  In 1986, Dr. Tetrisov&amp;#039;s theories were called into question when it was observed that the ant farms he had been studying did not contain any ants.  Dr. Tetrisov retired in disgrace and died three years later in an unfortunate collision with a muscular rickshaw driver.  However, his modeling program, Tetris, gained wide popularity as a simple puzzle game.   &lt;/div&gt;&lt;/td&gt;&lt;td class=&#039;diff-marker&#039;&gt;+&lt;/td&gt;&lt;td style=&quot;color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;&quot;&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;#039;&amp;#039;&amp;#039;Tetris&amp;#039;&amp;#039;&amp;#039;&amp;#039;&amp;#039;  is a [[puzzle video game]] originally designed and programmed by [[Dr. Igor Tetrisov]].

It was created on June 6, 1984, as the first model of ant colony structure and behavior.  Dr. Tetrisov was trying to model worker ant behavior he had observed in laboratory ant farms.  He observed that as the ants gathered food and building materials, they appeared to be organizing the materials into specific patterns.  He further observed that the ants seemed to be quite competitive and that the most successive organizers were awarded sweet juices from the queen and small pieces of straw.  The straw seemed to serve no purpose other than to be used by individual worker ants to tally &amp;quot;points&amp;quot; they had amassed in their organization game.  Dr. Tetrisov designed a simple game to mimic this observed behavior which he called Tetris.  Later, Dr. Tetrisov&amp;#039;s theories were called into question when it was observed that the ant farms he had been studying did not contain any ants.  Dr. Tetrisov retired in discrace.  However, his modeling program, Tetris, gained wide popularity as a simple puzzle game.  &lt;br /&gt;
